Making the hats seemed painstaking work. The palm leaves are stitched by hand to the frame, with tiny stitches. This lady told us she can make two a day. We bought one from her for 20,000VND (about $1 AUD or US).
The same village also produces incense, the sticks for which make an extremely colourful and photogenic display.
The sticks are handrolled into a paste of the required spices etc. I imagine there’s quite a market for incense in Vietnam, as every shop, business and restaurant (not to mention homes) would have a spot somewhere with a little temple with the sticks burning. In the mornings, shops would be hazy with incense smoke as the staff ‘smoked’ the store to drive out bad energy and make it a prosperous day.
